CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 263,114, dated August 22, 1882.

Application filed May 3, 1882. (No model.)

To all whom it may concern Be it known that I, Rossco CHAMBERLAIN, a citizen of the United States, and a resident of East Liberty,in the coun ty of Logan and State of Ohio, have invented a new and useful Improvement in Oar-Coupling Attachments, of which the following is a specification.

This inventionrelates to improvements in car-couplings of that class employing augerpointed or spirally-bladed draw-bars, and has for its object to effect the ready and easy coupling and uncoupling of the cars without cansin g the operator to pass between the cars, which is attended with great danger to life and limb.

The nature of this invention consists in the under side view thereof.

v A indicates the draw-head,having one chamber within which its draw-bar is arranged, and a second chamber to receive the head or free end of the draw-bar ofthe approaching car.

B is the draw-bar, having its inner end seated or supported in the draw-head, so as to rotate or turn, as shownin Fig. 2. Its outer end has a spirally-bladed or auger-pointed head. It is held under the action of a spring, a, by the recoilaction of which its movementisreversed, after having been turned in a certain direction by its passage into the draw-head, through the unoccupied opening thereof, to automatically effect the coupling operation.

(J is alever fixed to the revolving draw-bar B, and arranged to move in a slot, 1), cutting thedraw-bar diagonally across one corner. The lever G is so connected to the draw-bar as when at rest to extend therefrom about in line with the corner edge of the draw-head having the slot 1), as clearlyseen in Fig. 1. The lever G is connected, by a rod or chain or cord, D, to a cross-bar, 0, adapted to slide on the handled rod or lever E.

The rod E is supported and capable of being slid by hand in beaiin gs or eyes at, fastened upon the lower part of the car. This rod E has two projections or shoulders, 8, one arranged on each side of and a short distance from the slide 0, to enable the latter to act upon and move the rod E in either direction. The rod or lever E has a spring,f, which is adapted to enter one of the eyes d, supporting the rod or lever E, at a certain time, as seen in Fig. 2.

F is an upright shaft having a hand-wheel or lever, and suitably journaled in bearings fastened one upon the lowerpartof the carand the other to the top thereof.

A crank, g, is secured to the lower end of the shaft F, and connected to a rod, h, which is attached to the upper end of the slide 0.

It willbe observed that the coupling operation is effected automatically. This is caused by the turning of the draw-bar by the action of its spirally-bladed head against the beveled face or sides of the opening of the side chamber in the draw-head of the meeting car until the greater area of surface or width of the head of the draw-bar is brought in line with the length of the said opening. The instant this takes place the head of the draw-bar willpass through the opening of the aforesaid chamber of the draw-head and into said chamber. The drawbar will then turn upon its axis by the recoil action of its spring, so asto bring the greater area or width of its head behind the flanges formed by the sides of the opening of the side chamber of the draw-head, and thus effect the coupling operation.

The uncoupling of the cars may be effected either by turning the hand-wheel of the shaft F, which is desirable upon box or house cars, or by operating the handled'rod or lever E to allow such operation to be accomplished when the operator is standing on the ground and.

at one or either side of the cars.

To perform the uncoupling operation, turn the hand-wheel shaft F, or slide the handled rod or lever E so as to move the latter in a manner to cause its spring f to take into one of the eyes d, as shown in Fig. 2. This action of the rod will turn the draw-bar on its axis, so as to distend its spring a, while the spring f will hold the rod and draw-bar as against the action of the spring a. Thehead of the drawbar will be turned so as to present its greater width in line with that of the opening of the chamber in the draw-head, when by the movement separating the cars the draw-bar head will be released from the draw-head and thereby uncouple the cars.

The sudden jerking action produced by the separation of the cars and the liberation of the draw-bar will cause the release of the spring f and permit the reversing the rotation of the draw-bar by the recoil action of its spring a to return it to its original position, ready for a second coupling operation- Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a car-coupling, the combination, with the draw-bar having an auger-pointed or spirally-bladed head and its spring, of the lever arranged to project therefrom obliquely through the draw-head and move in a slot in the latter, the rod D, or its equivalent, connected to a'slide capable of striking either one of two projections or shoulders on a sliding rod adapted to be temporarily held by a spring, substantially as and for the purpose set forth.

2,. In a car-coupling, the combination, with the spring-actuated rotating draw-bar B,hav-

ing a spirally-bladed or auger-pointed head, of the lever 0, arranged to project therefrom obliquely through and move in a slot in the draw-head, the rod D, or its equivalent, the cross-bar or slide 0, and the sliding rod E, having shoulders e and-spring f, which enters a fixture on the car, substantially as and for the purpose set forth.

3. In a car-coupling, the combination, with the rotating draw-bar B, acted on by a spring, a, and the draw-head A,-having a slot, 11, through one corner, of the lever 0, arranged to extend from said draw-bar obliquely through the draw-head, rod D, or its equivalent, crossbar or slide 0, sliding bar or lever E, having shoulders 0 and spring f, adapted to be temporarily held by a fixture on the car, rod h, crank g, and hand-wheel shaft F, substantially as and for the purpose specified.
